The Magic Power System Power Bar plugs into your auto's 12V power port and is claimed to increase fuel efficiency up to 30 percent, increase torque and reduce emissions. Also said to improve car audio quality and "clean the entire car electrically," it costs just £35.

Just great! Another product that bites my internet handle, MPS. The other was the Mega Percussion Synthesizer and now this. Why can’t they call it the Power Magic System and then abbreviate it… Oh… I see.
